I got this off of honda tech, does this mean a 5857 is capable of 570whp?




"Im planning on using a 5557 for my 400-500whp build. Its rated at 54lb/min vs the GT3076r which is 53lb/min.

Heres a dyno on an EVO8:



5557 is red, 5857 is blue:"




~27psi

 

do the 5857. s2k head + motor super efficient. eats cfm up for dinner

5857 will meet your goals.

 

I'm sure Scorpion will comment he seems to know a boat load on these turbo's.

 

The 5557 made ~525whp, and the 5857 was 570whp, and that was on a 2.3 liter. The 5857 should make probably 570whp at ~20-22psi, depending on different factors.

 

i just purchased a 5857 but which would be better? .63 ar or .82 ar?

 

I'd say .82 if you like top end.

If it's a road racer, you prolly want the mid-range grunt, go w/the .64

 

Or you could go 6262 with a 0.63 A/R like I did so that I have some head room

 

Hey I thought you had a 6265 did you get another new turbo???

 

Yep, decided to just get another and sell mine with the IP Kit, who knows maybe I will try the 5857 just for fun??
